Well that was anticlimactic...
I am anticipating the follow up questions in local/regional clinics from the guys who never seem to grasp a rule change, no matter how straightforward.
"So, nobody on the defense can slap a guy in the head?" Nope, nor the offense
"So, the new rule is just the offense? The defense can do it now?" No, nobody can
"But they changed the rule, right?" Yes, so now nobody can
"Nobody on the offense?" Or the defense too!
[Expletive laden 20 minute rant about the free blocking zone deleted]
"What if he slaps in the shoulder, does that count?" *sigh*
